The 1000 Genomes Project SNPs and short indels were all submitted to dbSNP and longer structural variants to the DGVa.
Where possible, release VCF files contain the appropriate IDs in the ID column, such as dbSNP rs IDs.
The archives contain variants discovered by the final phase of the 1000 Genomes Project (phase 3) and also by the preliminary pilot and phase 1 stages of the project. As methods were developed during the project, phase 3 represents the final data set.
The longer structural variants predicted as part of the pilot project were submitted to the DGVa and given the accession estd59.
